Unusual coordination of tetraphenylborate to silver(I): synthesis and X-ray crystal structure of the complex N,N'-bis[3-(2-nitrophenyl)allylidene]ethane-1,2 diamine(tetraphenylborato)silver(I)

The complex N,N’-bis[3-(2-nitrophenyl)allylidene]ethane-1,2-diamine(tetraphenylborato) silver(I), [Ag(nca2en)(BPh4)], has been synthesized and characterized by CHN analyses and ¹H-NMR, IR and UV-vis spectroscopies. Its crystal and molecular structure was determined by X-ray diffractometry from singl...

More Information
Summary:The complex N,N’-bis[3-(2-nitrophenyl)allylidene]ethane-1,2-diamine(tetraphenylborato) silver(I), [Ag(nca2en)(BPh4)], has been synthesized and characterized by CHN analyses and ¹H-NMR, IR and UV-vis spectroscopies. Its crystal and molecular structure was determined by X-ray diffractometry from single-crystal data. The coordination geometry about silver(I) is best described as a distorted tetrahedron. The Ag center is covalently bonded to two N atoms of the Schiff base and two C atoms of tetraphenylborate. In the complex, tetraphenylborate shows an unusual behavior and acts as a bidentate ligand.
